 any running cron daemons on your system. If your old cron is not Vixie or
 accurately Vixie compatible (files in /var/cron/tabs*, /var/cron/allow,
 /var/cron/deny, /etc/crontab, /var/run/cron.pid) then you will need to clear out

+all old crontabs and make new ones afresh - or else look very carefully at the
+options you pass to the package configure script, as follows.
+
+It is often the case that GNU/Linux distributions and other Unices hacked the
+cron daemon to use different directories to those above. You can use configure
+options --spool-dir, --socket-file, --allow-file, --deny-file, --pid-file and
+--tmp-dir to make mcron behave similarly. Note that, with the exception of
+tmp-dir, none of these files or directories should be accessible by ordinary
+(non-root) users.
 
 If your old cron is Vixie, or very similar, mcron should fall right into place
-where your old cron was (the binaries cron and crontab will be replaced), and
-you should be able to continue to use your existing crontabs without noticing
-any changes. Bear in mind that if you use /etc/crontab, then changes to this
-file will *not* take immediate effect (this is the 1% incompatibility between
-mcron and Vixie cron); you may want to add a comment to this file with a note to
-this effect. Alternatively, use the new mcron program, it's better!
-
-If you don't want to clobber your existing cron executables, you can specify the
---program-prefix option to configure with a prefix ending in a non-alphabetic
-character, for example "m.", and then run the programs as m.mcron, m.cron and
